They say that man used to be way more in tune with nature. This picture would be good proof to that. These two buddies look like they're having a good time wrestling. At least, I assume that's what they're doing. That bear couldn't possibly be attacking that man. You know how I know that? Well, I don't KNOW that, exactly. The other option is that his friends are a bunch of dickheads. There's no way they are sitting back and filming their friend being attacked by a bear. Who would do that? That's why this human/bear pair must be friends.
Nowadays we have such easy access to stories about bears killing humans. Back in the day there weren't as many stories about it. If you met a nice bear you'd just think that everything would be fine. You wouldn't be thinking about that video you watched called, "Nice bears gone bad compilation."
